Methods and devices for transmitting data in the relay station and the base station

Abstract

A new data packet transmission solution is provided in the present invention. Firstly, a source network equipment sends a duplicate of a data packet to a sponsor relay station and other one or more assistant relay stations; then the one or more assistant relay stations transmit the duplicate of the data packet received to the sponsor relay station. After the sponsor relay station receives the duplicate directly transmitted by the source and a plurality of duplicates which are transmitted by one or more assistant relay stations, it applies a joint processing of several duplicates of the data packet, and then transmits the result of the joint processing to a corresponding network equipment. Preferably, after one or more assistant relay stations transmit the duplicates of the data packet to the sponsor relay station, the destination network equipment also receives one or more duplicates, and applies a joint processing of the one or more duplicates and a duplicate of the data packet which is received from the sponsor relay station.
